How to send #RequestParam in AJAX POST request

I have my API which accepts Request Param:
#PostMapping(value = "/export")
#ResponseBody
public ResponseEntity<String> bulkExport(
#RequestParam(value = "managedObjects", required = false) List<String> managedObjects) {
//data
}
);
I want to send AJAX POST request.
$.ajax({
type: "POST",
//url: "policy/js_policy",
url: "/export/ ,
async: false,
data: { "managedObjects": ["Audit","Logs"]},
contentType: "application/json; charset=utf-8",
dataType: "json",
complete: function (XMLHttpRequest, textStatus) {
//File Handling
}
});
I tried to send managedObjects in URL. In data also I am sending the same.But my API is not working. How to send the #RequestParam from AJAX POST request exactly?

pass a list in Query Param
$.ajax({
...
url: "/export?managedObjects=Audit,Logs" ,
...
});
pass a list in Request Body
$.ajax({
type: "POST",
url: "/export/",
...
data: {managedObjects[0]: "Audit",
managedObjects[1]: "Logs"}
...
});

Try stringifying your data:
var data = {
managedObjects: ["Audit", "Logs"]
}
$.ajax({
type: "POST",
url: "/export/",
async: false,
data: JSON.Stringify(data),
contentType: "application/json; charset=utf-8",
dataType: "json",
complete: function (XMLHttpRequest, textStatus) {
}
});
Additionally you should use "name" instead "value" in #RequestParam:
#PostMapping(value = "/export")
#ResponseBody
public ResponseEntity<String> bulkExport(
#RequestParam(name = "managedObjects", required = false) List<String> managedObjects) {
//data
}
);

I think the problem is just with list that you want to send in your request.
var dataToSend = {
list: [{ fieldname: 'ABC' }, { fieldname: 'DEF' }]; // your list should something like this.
$.ajax({
type: "POST",
//url: "policy/js_policy",
url: "/export/?managedObjects=" + Mos ,
async: false,
data: JSON.stringify(dataToSend),
contentType: "application/json; charset=utf-8",
dataType: "json",
complete: function (XMLHttpRequest, textStatus) {
}
});

Model is not attaching with controller in MVC using Ajax call?

I am trying to pass the model from view to controller using ajax AND when I check the value in the JS debugger model has data but it's not binding with controller and the controller model is showing null.
function BulkUpdate()
{
debugger;
var model = #Html.Raw(Json.Encode(Model.tags))
$.ajax({
type: 'GET', //GET
data: JSON.stringify({model}),
url: '#Url.Action("BulkUpdate", "Home")',
contentType: 'application/json; charset=utf-8',
dataType: "json",
success: function (data) {
$('#myModalContent').html(data);
$('#myModal').modal('show');
}
});
}
//and my controller code is
public ActionResult BulkUpdate(List<Tag> tags)
{
ModelAccessor obj1 = new ModelAccessor();
obj1.updatedDatas = new List<UpdatedData>();
foreach (var item in tags)
{
var tag = db.Tags.Where(x => x.Id.Equals(item.Id)).FirstOrDefault();
if (tag.TagValue != item.TagValue)
{
UpdatedData changedRow = new UpdatedData {
OldTagValue=tag.TagValue,
NewTagValue=item.TagValue.Trim()
};
obj1.updatedDatas.Add(changedRow);
}
}
return PartialView("_UpdateConfirmationBulk", obj1);
}

I have a solution.
function BulkUpdate()
{
debugger;
var model = #Html.Raw(Json.Encode(Model.tags))
$.ajax({
type: 'GET', //GET
data: {'tags':JSON.stringify({model})},
url: '#Url.Action("BulkUpdate", "Home")',
contentType: 'application/json; charset=utf-8',
dataType: "json",
success: function (data) {
$('#myModalContent').html(data);
$('#myModal').modal('show');
}
});
}
Try this because your method expects a parameter named tags and this is missing in you ajax call.

Can you try the type by post?
var model = #Html.Raw(Json.Encode(Model.tags))
$.ajax({
type: 'POST', //GET
data: JSON.stringify({model}),
url: '#Url.Action("BulkUpdate", "Home")',
contentType: 'application/json; charset=utf-8',
dataType: "json",
success: function (data) {
$('#myModalContent').html(data);
$('#myModal').modal('show');
}
});

How to simplfy the passing of parameter

I have these method in c# which requires 3 parameters
public void Delete_AgentTools(int ID,int UAM,int mode)
{
some code etc.
}
and I use javascript ajax to call this method and pass the parameter
function Delete_AgentTools(toolAccess, toolId, UAM) {
$.ajax({
type: "POST",
url: "IROA_StoredProcedures.asmx/Delete_AgentTools",
data: "{'toolAccess':'" + toolAccess + "', 'toolId':'" + toolId + "', 'UAM':'" + UAM + "'}",
contentType: "application/json; charset=utf-8",
dataType: "json",
success:function()
{
alert("Tool has been successfully delete");
},
error: function (XMLHttpRequest)
{
alert("error in Delete_AgentTools()");
console.log(XMLHttpRequest);
}
});
}
you see for me I want to simpilfy on how I pass the parameter in javascript. Is it possible to pass it as an object to the c# or simplify the passing of parameters in javascript

You can convert a js object as a JSON using JSON.stringify
var data = {};
data.toolAccess = value1;
data.toolId = value2;
data.UAM = value3;
$.ajax({
type: "POST",
url: "IROA_StoredProcedures.asmx/Delete_AgentTools",
data: JSON.stringify(data),
contentType: "application/json; charset=utf-8",
dataType: "json",
success:function()
{
alert("Tool has been successfully delete");
},
error: function (XMLHttpRequest)
{
alert("error in Delete_AgentTools()");
console.log(XMLHttpRequest);
}
});

function Delete_AgentTools(toolAccess, toolId, UAM) {
var data = {};
data.mode = toolAccess;
data.ID = toolId;
data.UAM = UAM;
$.ajax({
type: "POST",
url: "IROA_StoredProcedures.asmx/Delete_AgentTools",
data: JSON.stringify(data),
contentType: "application/json; charset=utf-8",
dataType: "json",
success:function()
{
alert("Tool has been successfully delete");
},
error: function (XMLHttpRequest)
{
alert("error in Delete_AgentTools()");
console.log(XMLHttpRequest);
}
});
No need to change in your C# code.

POST 400 error, ajax request

Why cant I save this, I get 400 (Bad Request),
and on headers response i get The CSRF token could not be verified.
$(document).ready(function() {
$("a#copylink").click(function (e) {
e.preventDefault();
var data = $('#campaign-form').serialize();
$.ajax(
{
contentType: "application/json; charset=utf-8",
dataType: 'json',
method: 'POST',
url: 'campaignsave',
data: data,
success: function(data){
alert(data);
}
}
)
});
});
on backend:
public function actionCampaignSave()
{
var_dump($_POST);
}

You can pass the [headers] parameter in your ajax call like this.
$.ajax({
url : 'campaignsave',
method : 'POST',,
headers : {
'X-CSRF-TOKEN' : $('input[name="token"]').val()
}
dataType : 'json',
data : data,
success : function(response) {
console.log(response);
}
});
Just make sure you've place {!! csrf_field() !!} on your [view] blade template to append the $(input[name="token"); html tag to get the token value to get the CSRF token as well. Hope this helps

Pass csrf token using headers property on ajax
$.ajax({
contentType: "application/json; charset=utf-8",
dataType: 'json',
method: 'POST',
url: 'campaignsave',
headers: { 'X-CSRF-TOKEN': 'token' }
data: data,
success: function(data){
alert(data);
}
});

Try this it may help you
$.ajax({
type: "POST",
url: 'campaignsave',
data: {test : data},
success: function(data) {
alert(data);
}
});

Get JavaScript Array in ASP.Net ArrayList as a parameter of a function

I am working on a project and have to send a JavaScript Array as a parameter of a ASP.Net function which parameter is ArrayList.
Below is my code,
JavaScript :
var propertyArray = new Array();
propertyArray.push("2");
propertyArray.push("3");
$.ajax({

contentType: 'application/json; charset=utf-8',
data: { propertyArray: propertyArray },
dataType: 'json',
success: function (response) {
var result = "Done";
alert(result);
}
});
Default.aspx :
[WebMethod]
public static bool SaveTextProperty(ArrayList propertyArray)
{
//Some code
return true;
}
Here I need to get JavaScript propertyArray as ASP.Net function named SaveTextProperty's parameter.
How can I get it?
Thank you.

You can use as follow
[WebMethod]
public static bool SaveTextProperty(List<string> arr)
{
//Some code
return true;
}
and jquery
var propertyArray = new Array();
propertyArray.push("2");
propertyArray.push("3");
$.ajax({
type: 'POST',
url: 'Default.aspx/SaveTextProperty',
contentType: 'application/json; charset=utf-8',
data: JSON.stringify({ arr: propertyArray }),
contentType: "application/json; charset=utf-8",
dataType: "json",
success: onSuccess,
failure: onError
});
function onSuccess(response) {
alert(response.d);
}
function onError() {
alert("fail");
}
